PH4201 - Pressure and Hydrostatic Depth Level Sensor The PH4201 Series submersible level sensors are specifically designed for pressure and hydrostatic level measurements of groundwater, wastewater, process liquids or sea water. Ideal for tanks, small size bore holes, wells, dams, irrigation, sewage, rivers or oceanography. The titanium housing provides immunity to virtually all environments, including brackish water, sludge or other chemicals better than most stainless steel transducers. The sensor’s polyurethane vented cable is molded to the sensor housing to provide the most reliable waterproof sensor proven in many applications. FEP cable is also available for oils or other chemical resistance. To avoid any cable elongation in Deep Well applications lengths down to 1000 feet, an integral Kevlar strand supports the sensor. A feature of the PH4201 is that it’s full scale range starts as low 0-30” WC, ideal for small tanks and water vessels. These sensors include a 1/2”-20 process connection under nose cone for external mounting to process fittings. Part Numbering Measurement Type P ‐ Pressure, H ‐ Hydrosta c Water Column Housing Materials Available Ranges Cable type P ‐ Polyurethane (Standard), F ‐ FEP (Op onal) Cable Length Input Voltage Great for water tanks, wastewater management, food and beverage, pulp & paper, industrial processing or pharmaceutical applications. Ideal for drop-in, continuous liquid level measurement and monitoring. Note: A Desiccant Filter or Bellows is recommended on the sensor breather tube to insure many years of reliable service. A Desiccant Filter, p/n PH-FIL is a recommended option with each pressure sensor. For years of maintenance free service, an environmental moisture seal can be purchased, Ask for p/n PH-EMS.

The PH4201 Series submersible pressure sensors are easy to hook up to most DC voltage supply from 12 to 32 VDC. Simply connect the supply in series with the Red (+) and Black (-) wires and an Ammeter or 4-20mA Panel Meter. Connect the Filter or Bellows to the vent tube. Then, drop the sensor into a tank, well or vessel, or remove the nose cone and thread into a 1/2”-20 process connection, with an O-ring, at the base of the liquid to be measured.
